Antifacist, styled "antifa," and Republican are adjectives like Christian. Christianity and the GOP are massive, documented networks with representatives and hierarchies.
So without a hierarchy, things scare you to the point of declaring them terroists?
So why aren't you screaming about the horrors of OSS and family parties?
(BTW Christianity does not have a hierachy, not a universal one anyway, some groups do of course, like the Catholics... but the baptists, various orthodoxies, and many many more groups don't recognize that hierarchy).
